GENERAL INFORMATION

M12701000001USA0000010000

The rear axle has the following features.

｠

The wheel bearing is a unit bearing (double-row
angular contact ball bearing) which incorporates the
oil seals and is highly resistant to a thrust load.

｠

The number of parts has been reduced by
integrating the magnetic encoder for ABS wheel
speed detection into the wheel bearing.

｠

ETJ-type on the differential side and EUJ-type on
the hub side constant velocity joints are featured in
the driveshaft.

｠

Adoption of the electronic control AWD optimizes
the size of the driveshaft constant velocity joint and
achieves the weight saving.

｠

Lead-free grease for the constant velocity joint has
been adopted.

｠

Hexavalent chromium has been eliminated from the
dust cover material.

｠

The electronic control coupling installed in front of
the differential, which transfers the drive force to the
rear wheels by pushing the clutch in according to

the strength of the magnetic attraction generated by
the magnetic coil (For more details, refer to
Electronic Control AWD ).

｠

Aluminum differential carrier is used for weight
saving.

｠

Optimization of the hypoid gear ratio reduces the
torque loss.

｠

Adoption of the hypoid gear with the same teeth
height realizes the downsizing and increases the
strength of the coupling.

NOTE:

EUJ (High Efficiency Compact Undercut Joint): The
lighter and smaller constant velocity joint compared
with the conventional BJ has been achieved by
adopting the eight small balls.
ETJ (High Efficiency Compact Tripod Joint): The
lighter and smaller constant velocity joint compared
with the conventional TJ has been installed.
